Abstract: The present study is devoted to the introduction of biometric identification systems in law enforcement. The author pays special attention to the phenomenon of computer handwriting, examining in detail the constitutional and legal aspects of the use of knowledge about it. For this purpose a wide methodological apparatus is used: comparative-legal method, method of analogy, deduction, method of modelling and others. The Russian practice and potential for further development are compared with the experience of foreign countries both in the regulation of general issues of biometric personal data and in situations of legal regulation of computer handwriting data. The author investigates how to simultaneously solve the problems of detection and investigation of offences in which printed texts act as evidentiary materials, and at the same time preserve human rights to privacy, personal and family secrecy, anonymity on the Internet. It is noted that computer handwriting is a rather young phenomenon for legal science; there is still no in-depth study of it from the perspective of this field of knowledge. This paper is only a beginning in understanding the topic under consideration. It raises basic questions: whether it is permissible to use knowledge about computer handwriting, how it should be protected and where it should be stored, whether it is necessary to limit the existing commercial interest in its use. As a result, the author comes to the following conclusions: it is permissible and necessary to collect information on computer handwriting, as this will reduce infringements on the natural rights of man and citizen. For such collection it is necessary to use a centralised state system in which all the requirements for the security of critical information infrastructure are implemented. However, before such a system is put into operation, it is necessary to support commercial companies in relevant developments and oblige them to provide information about users' computer handwriting at the request of authorised persons.

Abstract: The paper examines the issues of intuition in investigative practice. Relying on the positions of prominent forensic scientists, the importance of this heuristic mechanism for overcoming deadlocks caused not only by a shortage of information, but also by its overabundance is substantiated. The author suggests mechanisms for the development of intuition, the main of which is called the expansion of erudition, the accumulation of a large number of background knowledge.
The second part of the article discusses the problems of artificial intelligence. Firstly, the topic of its potential to replace a person is covered. Secondly, the position existing in science is refuted, according to which the work of artificial neural networks is characterized as intuitive.
  Based on the analysis of practical examples and the synthesis of various scientific positions, the author formulated the following conclusions:
1. The intuitive decisions based on the probabilistic assumption assist the investigator in choosing specific investigative actions or tactics for their conduct.
2. Intuition is best developed among investigators with average work experience and broad erudition.
3. Intuition can and should be developed, mainly by expanding erudition, accumulating background experience.
4. The work of artificial neural networks cannot be called completely intuitive, since they act according to a given algorithm, even if generating a solution that is not accessible to human perception, whereas intuition is a creative process that goes beyond standard models.
5. To date, there is only a weak artificial intelligence, which is able to cover only situations of an overabundance of information, but not its deficit, although the latter very often require an appeal to intuition.
6. Intuition is a competitive advantage of humans over artificial intelligence, allowing our species to think more broadly, more versatile.
